If you don't think it's front-page worthy, then just don't upvote. Flagging is meant for off-topic or spam, which this is clearly not.
That info by itself seems HN worthy as many of us have likely used Express as the "safe" choice when starting a new project. Time to rethink that...
As for the future of Express: I've only had the opportunity to get together with Doug in person once, but we've talked about this a few times in the past. I can guarantee you the last thing he wants is drama, so I'll leave the ball completely in his court there.
I will say this though: keep an eye on Doug's federated projects (jshttp and Pillar). Whether or not the various pieces are released as Express 5 or not, the _code base_ is still improving and becoming increasingly standardized, regardless of the monicker.

I've flagged it for mod review, I'm not sure if this should be on the front page, it doesn't seem like it meets the requirements for HN.
